  • Navigation device for joint replacement and surgical support device
    Patent number: 10213319
    Abstract: CT images near the pelvis are obtained before surgery, and a three-dimensional model of a pelvis part is created on a computer. The virtual three-dimensional bone model is used to plan an installation position of a guide instrument etc., and a virtual three-dimensional surgical site model including the guide instrument is constructed. Subsequently, during surgery, the guide instrument is installed, and three-dimensional images of a surgical site are obtained, and a measured three-dimensional surgical site model including the guide instrument is obtained. The virtual three-dimensional surgical site model and the measured three-dimensional surgical site model are compared, and an error between an ideal installation position of the guide instrument and an actual installation position of the guide instrument is detected to guide the operator to reduce the error.
